As well as what Diez has said, unless you absolutely want regexp's,
and by the sounds of it I'm guessing you may be after something more
flexible: what about the pyparsing module [1]. It handles your
situation quite nicely.

>>> import pyparsing
>>> parser = pyparsing.ZeroOrMore('-c')
>>> parser.parseString('-c-c-c-c-c-c')
(['-c', '-c', '-c', '-c', '-c', '-c'], {})

hth,
Jon.
